I am really thinking about getting rid of the Optimas and going to 2 Interstate 6v Golf Cart Batteries. I am running 3 amps that combined are pushing 1680 watts to my speakers. 2 of the amps are at 2 ohms and 1 is at 4ohms. Amps are the Arc Audio KS with class H technology.

Are the golf cart batteries going to be able to keep up with the system in terms of power demand. (Will the fluctauting power demands from the sub be greater than what the batteries can provide?)

I really don't want to have to add a Stinger 5 farad capacitor but I will if absolutely necessary.
